Your Result

Clear Daily Protein Breakdown

Understand exactly how much protein to consume daily and how to space meals for optimal muscle protein synthesis.

01

Total Daily Protein Range

Lower and upper target bounds in grams per day.

02

Per-Meal Distribution

Recommended protein dose per meal based on your meal frequency.

03

Protein Source Recommendations

High-leucine food and supplement suggestions matching your diet style.

04

Renal & Health Safety Notes

Medical considerations for individuals with kidney history.

Evidence-based methodology
Myofibrillar Protein Synthesis (MPS) & Nitrogen Balance Model
Proteins supply essential amino acids (especially Leucine) to stimulate mTORC1 signaling and muscle protein synthesis. Research from ISSN and BJSM indicates an optimal daily intake range of 1.4–2.2 g/kg for active males depending on training volume and energy deficit.
